Preparing items for chrome plating
laidback:
Well, i took your advice people.
Yesterday i took delivery of some Oxalic Acid (£3 from Ebay) and set to work!
Firstly i removed the grips and cleaned the bars with soapy water. I then blasted out all the crap from inside the bars with my compressor.
Here's how they looked before the bath:
I then added a few heaped tea spoons of the Acid to a tub of water, with the parts placed in it and left it for about 6 hours. The Water goes cloudy and gives off an eggy smell, so i did this in my garage, which is well ventilated.
I checked on them after 6 hours, and then because i couldn't sleep, i gave them a stir and added a bit more acid at 5 am!
After about 18 hrs, the container looked like this:
I then removed the parts and scrubbed the rusty areas (most of it had disappeared) with a tooth brush and old scouring pad.
They were rinsed in fresh water thoroughly.
This is what i was left with after a clean and a polish:

Bars Afterwards:
As you can see, the bars are far from perfect, but much better. They will be good enough to be painted, and it required little effort. OA baths are a neat trick :daumenhoch:

If you get them stripped, polished and re-chromed you could lose lots of weld detail and the Haro Chevron detail.
Have a look in the sticky section for some guidance.
